Some people may be aware of DeCSS, a bit of C of which the MPAA (and the rest of the US gov't) are not very fond because it decrypts copy- and read-protected DVDs for playing on, say, linux machines where no such license is available.
I had the idea for a code-golf challenge along the lines of "write the shortest DeCSS-er or brute-forcer" but before properly writing up a challenge for the sandbox, it occurred to me that perhaps the community would not take kindly to the posting of a challenge which may or may not break a law (not really) or probably enrage a lawyer somewhere.
Can I propose such a challenge?
